A Smoke Chamber Test, also known as a smoke test or smoke puffer test, is a method used to visually identify air leaks and draughts in a building or specific area. It involves using smoke to create a visible indicator of air movement and to identify areas of air infiltration or exfiltration.
During a Smoke Chamber Test, a smoke source, such as a smoke pencil, smoke stick, or smoke generator, is used to release a controlled amount of smoke into the environment. The smoke is then observed to determine its movement and any signs of air movement or leakage.
The smoke is drawn towards areas of air movement, highlighting draughts, air leaks, or gaps in the building envelope. It helps identify locations where air may be entering or exiting the building, such as around windows, doors, electrical outlets, plumbing penetrations, or other potential openings.
Smoke Chamber Tests are particularly useful for localised testing and pinpointing specific areas of concern. They provide a visual indication of air movement and can help guide air sealing efforts and improve energy efficiency.
It is important to note that the smoke used in a Smoke Chamber Test should be non-toxic and safe for use in a specific environment. Safety precautions and proper ventilation should be followed to ensure the well-being of occupants and the environment.
While Smoke Chamber Tests provide a qualitative assessment of air leaks and draughts, more quantitative methods, such as blower door tests or infrared thermography, may be necessary to measure the extent of air leakage and quantify the airtightness of the building.
